WARNING
!
The naked part of the wire core should be 10 mm and fi x it

to the terminal tightly. Then try to pull the individual wire to
check if the contact is tight. Improper insertion may burn the
terminal.
Be sure to use only power cables approved from the authorities
●
in your country. For example in Germany: Cable type: NYM
3x1.5mm2.
Please refer to the installation manual for wire connection to
●
the terminals of the units. The cabling must meet the standards
of electrical installation.
There is a AC voltage of 230V between the L and N terminals.
●
Therefore, before servicing, be sure to remove the plug from
the AC outlet or switch off the main switch.
1
Insulation And Maintenance Of Pipe Connection
The connected terminals should be completely sealed with heat insulator and then tied up with rubber
●
strap.
Please tie the pipe and power line together with vinyl tape as shown in the fi gure showing the installation
●
of Indoor and Outdoor units. Then fi x their position with holders.
To enchance the heat insulation and to prevent water condensation, please cover the outdoor part of
●
the drain hose and pipe with insulation pipe.
Completely seal any gap with putty.

Installation Of Remote Controller
The remote controller can be placed in its holder
●
which is fi xed on wall or beam.
To operate the remote controller at its holder, please
●
ensure that the unit can receive signal transmitted
from the controller at the place where the holder
is to be fi xed. The unit will beep when signal is
received from the remote controller. The signal
transmission is weaken by the fl uorescent light.
Therefore, during the installation of the remote
control holder, please switch on the light, even
during day time, to determine the mounting location
of the holder.
Operation Test
Please ensure that the air conditioner is in normal operating condition during the operation test.
●
Explain to your customer the proper operation procedures as described in the user's manual.

CAUTION
!
Please use a new socket. Accident may occur due to the use of old socket because of poor contact.
●
Please plug in and then remove the plug for 2 – 3 times. This is to ensure that the plug is completely
●
plugged into the socket.
Keep additional length for the power cord and do not render the plug under external force as this
●
may cause poor contact.
Do not fi x the power cord with U-shape nail.

Wiring Of The Indoor Unit
For wire connection of the Indoor unit, you need to
●
remove front panel and electrical cover.
Method to remove front panel
Refer to "FINAL STAGE OF INSTALLATION – How to
●
Remove The Front Cover".
Method to remove the low cover
Pull the cover at
and
in the directions as
●
shown by arrows to remove the cover.
Checking for the electric
source and the voltage range
Before installation, the power source must be checked
●
and necessary wiring work must be completed. To make
the wiring capacity proper, use the wire gauges list below
for the lead-in from a pole transformer and for the wiring
from a switch board of fuse box to the main switch and
outdoor unit in consideration of the locked rotor current.

Removal Of Air From The Pipe And Gas Leakage Inspection
Procedures of using Vacuum Pump for Air Removal
As shown in right fi gure, remove the cap of valve core. Then, connect the charge hose.
1
Remove the cap of valve head. Connect the vacuum pump adapter to the vacuum pump
and connect the charge hose to the adapter.
Fully tighten the "Hi" knob of the manifold valve and completely unscrew the "Lo" knob.
Run the vacuum pump for about 10~15 minutes, then completely tighten the "Lo" knob
